UNITED STATES CARL THEO. OSTERBERG, OF MILWAUKEE, WISCONSIN.

WRENCH.

Appflioation filed March 30, 1922.

To all whom it may concern Be it known that I, CARL THEODOR OsTnR- BERG,a citizen of the United States, and a resident of the city of Milwaukee,county of Milwaukee, and State of WVisconsin, have invented certain newand useful Improvements in renches; and I do declare the following to bea clear, exact, and complete description thereof, such as will enablepersons skilled in the art to which the invention relates to make anduse the same, reference being had to the accompanying drawing, asshowing a practical embodiment of my 1nvention.

My invention relates particularly to wrenches suitable for gripping andholding cylindrical objects. It has been my object to produce a wrenchwhich can be used with, and without damage to, such articles as fruitjars, finished or nickel plated pipes used in connection with plumbingfixtures, etc. i

I have illustrated some forms of construction, suitable for a wrench tobe used for holding fruit jars, etc., but it will be understood thatthis may be modified in order to secure sufficient strength or betteradaptability for other uses.

In the drawing which accompanies this specification,

Figure 1 is an isometric perspective showing the wrench in inoperativeposition, as applied to a jar or other cylinder.

,Fig. 2 is a plan view showing the wrench in operative position.

Fig. 3 is an end view in elevation of the wrench showing the angularextensions of the handle with the sleeves encircling the same, spaced soas to provide a slot in the end of the wrench.

Fig. 4 is a perspective View of a modified form of construction in whichthe slot is formed in the front end of the wrench, with out using thesleeves shown in Fig. 3.

In the drawing, referring to Figs. 1, 2 and 3, a handle 10 made from ametal strip bent at its middle into U shape with parallel members 11, isprovided with spaced projections 12. These projections are bent at aright angle to the plane of the members 11, and their free ends approacheach other in the manner shown in Fig. 3, the projections from eachmember being encircled by a sleeve 13 to cover the joint at the meetingends and present a smooth surface over which the flexible strap, to belater referred to, may move without engagement of the strap with theends Serial No. 547,992.

of the said angular projections. The projections and their enclosingsleeves stand transversely aligned with respect to the handle to presenta widened front end, and a vertical slot opening in the direction of thelength of the handle is formed between the said aligned parts.

After the projections 12 have been entered in the sleeves and themembers 11 brought into parallelism, the said members are permanentlyconnected so as to fix the structure by means of a rivet or post 14. Asleeve 15 may be placed about the rivet 14, and serve as a distancepiece for the members 11 when the ends of the rivet 14 are upset.

A flexible strap 16 is looped about and attached to the post 14:, andthe free end of said strap is passed from the rear through the verticalopening or slot between the sleeves 13 at the front end of the handle. Aloop will be formed in the slack portion of the strap between thesleeves 13 and the post 14, such loop then being placed over a jar orcontainer 17, when the wrench is used to hold a jar or container. Inusing the wrench to grip a pipe or other object so located that the loopin the strap 16 cannot he slipped over the end thereof, it will benecessary first to loop the strap about the object before passing thefree end through the space between the sleeves.

After being applied in either of the manners described the projectingfree end of the strap is pulled taut, with the wrench in the relativeposition shown in Fig. 1. Thereupon the handle 10 will, be given amovement of rotation about the object encircled by the strap, into theposition shown in Fig. 2, so that the strap will be tightly drawn aboutthe object for almost its entire circumference. In such movement, therear sleeve 13 will be encircled by the strap. Pressure applied to thehandle 10 to effect the rotative movement described will cause the frontsleeve 13 to pinch the layers of the strap, in the manner illustrated inFig. 2, so that slipping thereof is prevented. In such position thefront sleeve 13 acts as a fulcrum for the handle 10, so that thefrictional engagement of the strap with the object is increased by thefurther rotation of the handle. The engagement thus elfected issufficient to cause rotation of the object, or to prevent its rotationin case a contrary force be applied.

Fig. 4 shows a modified construction of the wrench.
